What you get with a South Dakota lookup
- South Dakota SOS entity record — name, status, entity type, formation date, registered agent + address, principal office, and officers/managers where the state exposes them.
- USDOT / FMCSA carrier verification — for trucking deals, we pull the carrier's authority status, MC#, fleet size, MCS-150 history, and BASIC scores. Auto-matched to the SOS legal name when applicable.
- OFAC SDN screening — every search runs the company name against the Treasury sanctions list. Clear-result PDFs are signed.
- DBA / Fictitious Name registries — surfaces the county/town clerk where this entity would file a DBA in South Dakota, plus the statewide registry when one exists.
- One merged PDF — cover sheet + SOS record + USDOT snapshot + supporting docs, all in a credit-file-ready packet.
How South Dakota files business entities
South Dakota's SOS portal at sosenterprise.sd.gov was upgraded in 2019 and is fully modern. The search is reCAPTCHA-gated and returns entity name, ID, status, and registered agent. South Dakota has become a trust-formation hub thanks to favorable trust laws — many of those trusts own LLCs registered in the state.

How DBAs work in South Dakota
South Dakota files Fictitious Business Names at the state SOS exclusively — no county-level DBA filing. The same search returns entities and Fictitious Name records. Sioux Falls hosts more credit-card company LLCs than any other US city, thanks to South Dakota's 1980 usury-cap repeal.
Credit-underwriting gotchas in South Dakota
South Dakota LLCs owe a $50 annual report due on the formation anniversary. Missed reports trigger 'Delinquent' status after 60 days past due, and 'Administratively Dissolved' after a year. South Dakota law has no maximum interest rate for loans, which is why every major US credit card company has a South Dakota entity — be aware that an SD-registered entity may carry consumer-finance lending operations even if the public filing suggests otherwise.

✓ South Dakota is covered
VerifySOS pulls the South Dakota SOS record for you automatically — no manual lookup, no PDF upload. SD sits behind a slower portal (or a captcha we solve on your behalf), so results typically land in under a minute rather than instantly. USDOT, OFAC, and county DBA lookups run automatically alongside it.
